In the progress of tumor development, it shows heterology, and formed different subgroup, promote metastasis.

其表现为肿瘤在组织形态学、核型，免疫表型，遗传标志物，生长率，细胞产物，药物敏感性以及其他细胞组织学特征方面呈现广泛的多态性，从而产生不同转移能力的癌细胞。

Rats were killed after different weeks(0,1,2,4,8,12,15,17,19,20 and 24 respectively). Their organs were taken to observe the kinetic change of selenium concentration, the activities of intracellular glutathione peroxidase,extracellular glutathione peroxidase, and phospholipid hydroperoxide glutathione peroxidase in different organs.

于0、1、2、4、6、8、12、15、17、19、20和24周时处死大鼠取其组织，分别对各种组织中的硒、细胞内谷胱甘肽过氧化物酶、细胞外谷胱甘肽过氧化物酶、磷脂氢谷胱甘肽过氧化物酶、Ⅰ型脱碘酶和Ⅱ型脱碘酶活性进行动态观察。

Results:The main manifestation of A group was transient hepatocyte hydropic degeneration; in group B the degeneration of hepatocytes was most severe in the 2nd week. Fibrosis appeared in the 4th week,and obvious pseudolobules were formed in some parts of the liver in the 6th week.

结果：A组HE染色肝细胞呈一过性水样变，变性在2周时最重，至6周已明显减轻。B组HE染色2周时肝细胞明显水样变，4周时可见汇管区纤维组织增生，6周时部分肝组织出现明显假小叶结构。

Histological analysis From day 14 after the operation, osteoblast-like cells appeared in clusters adjacent to vascular sinuses on either side of the fibrous interzone.

组织学分析术后第十四天，在延长部的纤维组织血管窦附近，可见成簇存在的成骨细胞样细胞，并可观察到类骨组织样基质的出现。

RESULTS: After 2×104 of Sca-1+ cells were transfused, the hematopoietic function in the lethally irradiative female mice was completely restored.

目的：探讨在同种异体造血重建中组织辐射损伤与胎肝Sca-1+细胞及其子代细胞移植后在不同组织器官分布差异的联系。

The oil cells are mainly distributed in the palisade tissue in the leaves of 47 species and in the spongy tissue in the leaves of 5 species, and dispersed in the whole mesophyll in the leaves of 31 species.

油细胞是木兰科植物叶片解剖的显著特征，在叶肉中的分布可划分为三种类型：油细胞主要分布于栅栏组织；主要分布于海绵组织；均匀散布于整个叶肉中。

By in situ hybridization, 53BP2 mRNA expression is revealed in tumor cell nests of NPC paraffin sections. The strong positive particles localize in the nuclei of tumor cells; but slight positive signals are also found in tissue cells of chronic nasopharyngitis and connective tissue, such as lymphocytes and smooth muscle cells; There are also positive signals in the nuclei of hyperplastic squamous epithelial cells. However, 53BP1 mRNA expression is not found in nuclei of tumor cells, tissues of chronic nasopharyngitis and connective tissue.

原位杂交结果显示，石蜡切片的鼻咽癌癌巢内，可见53BP2的强阳性表达信号，信号呈紫色颗粒状分布于胞核，核仁清晰可见；而在相同条件下，在慢性鼻咽炎组织和癌旁上皮的结缔组织，也可见弱表达信号，如淋巴细胞和平滑肌细胞；在增生的鳞状上皮细胞的核内，可找到强阳性信号。53BP1在鼻咽癌、慢性鼻咽炎组织和癌旁上皮的结缔组织切片上，均无表达信号。

It was conferred that neuroglia cells restrained the apoptosis of target tissue,and then afforded the probability to nerve regenerated to target issue.

推测可能是由于神经胶质细胞的作用，提前抑制了靶组织的细胞凋亡，从而为神经再生回靶组织提供条件。

The research of cytology shows that there are dramatically morphological and structure changes in the leaf: the cells of mesophyll array loosely and parenchyma cells reduced, cambium becomes thinner and degree of xylem becomes more serious, the content of chlorophyll dropped; the changes of conducting tissue and stoma structure affect transport and allocation of water and nutrient, hinder leaf growth and disturb regular metabolism of leaf, at last lead to wilt, rot and become crisp papyraceous.

细胞学研究表明，病叶组织的叶肉细胞排列疏松，薄壁细胞层次减少，形成层变薄，木质化程度加深，叶绿体减少；在病叶中由于疏导组织和气孔的结构发生变化，影响养分和水分在植株体内的运输和分配，干扰叶片的正常代谢，抑制叶片的生长发育，最终导致叶片失水萎缩、干枯，变为焦脆的干纸状。

In addition to β cells,GIP receptor is also expressed in various tissues including stomach, small intestine, adipose tissue, adrenal cortex, pituitary body, bone, vascular endothelial cells and brain.

而许多研究证实GIP受体分布广泛，除分布在胰腺β细胞外，还分布于胃、小肠、脂肪组织、肾上腺皮质、心脏、肺、垂体、骨、血管内皮细胞和脑组织的一些区域等，在这些组织中发挥重要的作用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
